The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. how many ergs of radiant energy does the sun produce in 3.25 ⋅ 10^3 seconds?

The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second.
How many ergs the sun produce in 3.25 ⋅ 10^3 seconds

3.9 ⋅ 10^33 x 3.25 ⋅ 10^3
= (3.9 x 3.25)(10^33 x 10^3)
= 12.675 x 10^36
= 1.2675 x 10^37

answer
1.2675 x 10^37 ergs of radiant energy the sun produce in 3.25 ⋅ 10^3 seconds

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
